错误：未找到“PHPMailer\PHPMailer\Exception”类

Question

我有一个（也许是愚蠢的）问题。由于我是新手并且已经尝试了几种解决方案，所以我现在在这里寻求有关脚本的帮助。

我正在使用这个脚本来生成 LetsEncrypt 证书。它已经工作了五年多，但今天在订购过程中通过终端提示我以下消息：

550: Failed to spawn mail-process (ec:16) Error: Class "PHPMailer\PHPMailer\Exception" not found

这是触发的脚本的相关部分：

###sending it as email:
##########################################################
# sendCertificate
##########################################################
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;
include('PHPMailer.php');

function sendCertificate($myemail) {
    global $argv;
    global $account_number;

    $email = new PHPMailer();
    $email->setFrom($myemail); //Name is optional
    $email->Subject   = 'ssl certificate files';
    $email->Body      = "
https://kis.hosteurope.de/administration/webhosting/admin.php?menu=6&mode=ssl_list&wp_id=$account_number
Zertifikat: fullchain.pem
Key: cert_private_key.pem
";

    $email->addAddress($myemail);
    
    $file_to_attach = __DIR__ . '/'.$argv[3];
    $email->addAttachment($file_to_attach , $argv[3]);
    $file_to_attach = __DIR__ . '/fullchain.pem';
    $email->addAttachment($file_to_attach , 'fullchain.pem');
    
    $sent = $email->send();
    if($sent) {
        echo "sending certificates by mail ... OK\n";
    }
    else {
        echo "sending certificates by mail ... ERROR\n";
        print_r( error_get_last() );
    }
}
sendCertificate($argv[1]);


?>

顺便说一句，我在 GoDaddy 托管的网络空间上。服务器是 PHP 8.1。该脚本自几周前运行以来一直没有更改。

谢谢！

最好

我尝试将 PHPMailer.php 更新到最新版本。

我通过更新 PHP Mailer、创建新的 SMTP 帐户并更新脚本解决了问题：

    // Manually loading the necessary PHPMailer classes
require 'PHPMailer.php';
require 'SMTP.php';
require 'Exception.php';

function sendCertificate($myemail) {
    global $argv;
    global $account_number;
    global $domain_id;

    $email = new PHPMailer();

    try {
        //Server settings
        $email->isSMTP();                                            // Send using SMTP
        $email->Host       = '+++';      // Set the SMTP server to send through
        $email->SMTPAuth   = true;                                   // Enable SMTP authentication
        $email->Username   = '+++';                       // SMTP username
        $email->Password   = '+++;                           // SMTP password
        $email->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;         // Enable TLS encryption; `PHPMailer::ENCRYPTION_SMTPS` also accepted
        $email->Port       = 587;                                    // TCP port to connect to

        // Recipients and content
        $email->setFrom($myemail); // Name is optional
        $email->Subject = '+++';
        $email->Body = "
https://kis.hosteurope.de/administration/webhosting/admin.php?menu=6&wp_id=$account_number&mode=sslupload&v_id=$domain_id
Certificate: fullchain.pem
Key: cert_private_key.pem
";
        $email->addAddress($myemail);

        $file_to_attach = __DIR__ . '/' . $argv[3];
        $email->addAttachment($file_to_attach, $argv[3]);
        $file_to_attach = __DIR__ . '/fullchain.pem';
        $email->addAttachment($file_to_attach, 'fullchain.pem');

        if ($email->send()) {
            echo "Sending certificates by email ... OK\n";
        } else {
            echo "Sending certificates by email ... ERROR\n";
        }
    } catch (Exception $e) {
        echo "Sending certificates by email ... ERROR: ", $email->ErrorInfo, "\n";
    } catch (\Exception $e) {
        echo "General error: ", $e->getMessage(), "\n";
    }
}

sendCertificate($argv[1]);
